4.34 Physical Request Filter High Register

The physical request filter high set/clear register enables physical receive requests on a per-node basis, and handles

the upper node IDs. When a packet is destined for the physical request context, and the node ID has been compared

against the ARRQ registers, then the comparison is done again with this register. If the bit corresponding to the node

ID is not set to 1 in this register, the request is handled by the ARRQ context instead of the physical request context.

The node ID comparison is done if the source node is on the same bus as the TSB12LV26 device. Nonlocal

bus-sourced packets are not acknowledged unless bit 31 in this register is set to 1. See Table 4−26 for a complete

description of the register contents.

4.35 Physical Request Filter Low Register

The physical request filter low set/clear register enables physical receive requests on a per-node basis, and handles

the lower node IDs. When a packet is destined for the physical request context, and the node ID has been compared

against the asynchronous request filter registers, then the node ID comparison is done again with this register. If the

bit corresponding to the node ID is not set to 1 in this register, the request is handled by the asynchronous request

context instead of the physical request context. See Table 4−27 for a complete description of the register contents.
